Propagation de la lentille sphérique mince et légère Matériau Ge Double lentille concave
Double Concave (Bi-Concave) Spherical Lens, N-BK7, Spread Light Overview: Double-Concave (DCV) Lens, also referred to as bi-concave lens, has two inward curved surfaces. They have a negative focal length and are best used to diverge a converging beam. Double-concave lenses can diverge a collimated beam to a virtual focus and are commonly used for image reduction and to spread light. Star Optic provides double-concave lenses in a variety of substrates and anti-reflection

Positive Meniscus Lens, N-BK7, Low Spherical Aberration Lens Overview: Positive meniscus (convex-concave) lenses are designed to minimize spherical aberration. When used in combination with another lens, a positive meniscus lens will shorten the focal length and increase the numerical aperture (NA) of the system without introducing significant spherical aberration. When used to focus a collimated beam, the convex side of the lens should face the source to minimize spherical

Plano Concave (PCV) Spherical Lens, UV Fused Silica, Diverging Collimated Beam Overview: Plano-concave (PCV) lens has one flat and one inward curved surface. PCV lenses have a negative focal length, diverging a collimated beam from a virtual focus and are commonly used for image reduction or to spread light. Star Optic provides plano-concave lenses fabricated from N-BK7, N-SF11, UV-fused silica, calcium fluoride, zinc selenide and etc. General Specifications Of UV Fused

Double Convex (Bi-Convex) Spherical Lens, UV Fused Silica, Finite Imaging Lens Overview: Double-Convex (DCX) Lens, also referred to as bi-convex lens, has two positive, symmetrical faces with equal radii on both sides. These lenses are generally recommended for finite imaging applications. Bi-convex lenses are most suitable where the object and image are on opposite sides of the lens and the ratio of the image and object distances (conjugate ratio) is between 0.2 and 5. Star

Positive Achromatic Lens, Spherical Aberration Lens Overview: An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue) into focus on the same plane. The most common type of achromat is the achromatic doublet, which is composed of two individual lenses made from glasses with different amounts of dispersion. Typically, one element is a

Plano Convex Cylindrical Lens, Rectangular, UV Fused Silica Overview: The Plano Convex Cylindrical Lens is also identified as positive cylindrical lens. They are ideal for applications requiring magnification in one dimension. While spherical lenses act symmetrically in two dimensions on an incident ray, cylindrical lenses act in the same manner but only in one dimension. A typical application is to use a pair of cylindrical lenses to provide anamorphic shaping of a beam. A
